ABSTRACT:
A proportional solenoid actuated servo system and associated drive circuitry are disclosed in which a pair of oppositely acting coils of the solenoid are connected in series across a floating power supply with the center point between the coils grounded. The voltages produced at the power supply terminals are differentially controlled relative to ground by voltage control means which responds to position command and armature position feedback signals. The force exerted by the armature is controlled by a power control signal which varies the voltage difference between power supply terminals.
